Patented Nov. 22, 1910.

To all whom it may concern:

Be it known that I, HENRY B. COLLIER, a citizen of the United States, residing at Prairie Grove, in the county of Washington, State of Arkansas, have invented certain new and useful Improvements in Conductor- Strips; and I do hereby declare the follow ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to conductor wires and has special reference to a conductor strip adapted to be used with burglar and other alarms.

The object of the invention is to provide an improved article of manufacture which may readily be attached to glass surfaces and which will embrace a conductor strip adapted to be used as part of a closed circuit alarm.

With the above and other objects in view the invention consists in general of a strip of conducting material rovided with improved means for'att-achlng the same to a surface.

The invention further consists in certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings, and specifically set forth in the claims.

In the accompanying drawings, like char acters of reference indicate ,like parts in the several views, and :Figure' 1 is a face vlew of a window equipped with thisinvention. Fig. 2 is a section throu h the window glass showing the device applied. Fig. 3 is a perspective view of a strip of this character before application. Fig. 4 is a section therethrough.

Thenumeral 10 indicates the sash of, a

-window and at 11 is shown the window glass. Located on the sash is a suitable contact device 12 from which extend wires 13. Soldered or otherwise connected to the wires 13 is a metallic strip preferably in the form of a flat ribbon ofconducting material such as tinfoil as indicated at l4. This strip is secured to a fabric strip 15 which extends longitudinally of the first or conducting like.

strip and has its lateral edges projecting well over said conducting strip. These lateral edges are gummed .on the face to which the conducting strip is attached.

In using this stripit is merely necessary to moisten the gummed edges and extend the strip backward and forward across the window as is clearly shown in Fig. 1. It is to be understood that the window. here shown is typical of any structure which it is desired to wire such as a door, lattice or the This'strip is designed to be manufactured with the conducting material applied to the fabric and it is preferred that the fabric shall be of the nature of paper or the like.

From the foregoing it will be observed that the strip may readily be applied in any form'to any surface wh1ch it is desired to protect.

It will be noted that this strip is especially adapted for closed circuit burglar alarms. It is'well understood that insu'ch alarms the signal is actuated by the breaking of a circuitcovering a place to be protected. It is also well known that with ordinary wires the circuit may be short circuited and the glass-or other surface cut out between the short circuitpoints. In the present invention, owing to the peculiar construction of the strip the same cannot be short circuited as any attempt to get at the metallic conductor will result in breaking the conductor strip.

It is obvious that minor-changes may be made in the form and construction of this invention without departing from the material principles thereof. It is not therefore desired to confine the invention to the exact form herein shown and described, but it is wished to include all such as properly come within the scope of the appended claims.

Having thus described the invention, what is claimed as new, is v 1. A wiring for burglar alarms comprising a part to be protected, conductor strips extending continuously across the part to be'protected, and gummed strips pasted over the conductor stri s and to said part, said gummed strips being pasted to the conductor strip and extending unbrokenly the enalso gummed for attachment to a surface on tire length here0f, and sai conductor strip the side facing the conductor strip. 10 being a strip of metallic fail.
